Statement - 1: For a mass $M$ kept at the centre of a cube of side ‘$a$ ’, the flux of gravitational field passing through its sides is $4\pi GM$.Statement - 2: If the direction of a field due to a point source is radial and its dependence on the distance ‘$r$ ’ for the source is given as $1/r^2$, its flux through a closed surface depends only on the strength of the source enclosed and not on the size or shape of the surface.
